In order:Ceridwen - This is by far my favorite with Rosalind and if we assume you get pregnant again when Roo is about 10-11 months old (fingers crossed) then she'd be that beautiful winter-fairy you mentioned a few months ago. CeridwenOphelia Alcyon though I'm sure your BF/FI would prefer a "normal" name in there so CeridwenFiammettaIsobel or Cerdiwen Elvira Alcyon. (Does Elvira count as "normal"?)Zenobia - Second choice. Roo and a summer Zenobia would be brilliant. ZenobiaAtlantaMatilda (I know your friend already has one but does that mean it's out as a mn?) or ZenobiaNatashaOphelia would be beautiful.Fiammetta - I still love this and think it's stunning but is it too frilly in comparison to Rosalind? (Does it make Rosalind feel less girly?) I think this could make a brilliant mn to counter Illyria.

9 months? Whew... you have more lady cojones than me. Rowan is 18 months and some days I think this summer might be too early to start TTC... she is going through a "throws a tantrum over everything" phase and it's wearing me out.

What about Melusine/Melusina, the french version of Melisande? There's a Luxembourgish fairytale surrounding Melusine in which she's half human and half serpent and marries a king. She curses a city and... I think it'd be better if you looked it up. I'm bad at explaining it. Melusine, unbenownst to almost all, is the starbucks insignia. The imagery I think of when I hear Melusine is stunning.

Melisande may also be slightly too close because of the shared nd ending/3 syllables with Rosalind.
